Is the blowing process of the plastic bottle blowing machine environmentally friendly?

Update:29 Oct 2020

   At present, most of the blow molding machines are still two-step blow molding machines, that is, it is necessary to first make plastic raw materials into preforms, and then blow them. Nowadays, environmentally friendly plastics made of PET are generally used.

The blowing process is divided into two parts:

   One, warm up

  The preform is irradiated through a high-temperature lamp, and the body part of the preform is heated and softened. In order to maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so a certain cooling device is required to cool it.

   2. Blow molding

  In this stage, the preheated preform is placed in the ready-made mold, and the preform is inflated under high pressure to blow the preform into the required bottle.

   Bottle blowing machines on the market are generally divided into two types: automatic and semi-automatic.

  The automatic bottle blowing machine combines the two operations of bottle blowing through the operation of the manipulator, eliminating the need for the center to manually put the preheated preform into the mold. Greatly speed up the production rate, of course, the price is also higher than the semi-automatic.

   The food industry is developed, and the food and beverage packaging profession is also expanding. Also affected the blow molding machine career. The blow molding machine profession is facing a big problem in China:

   1. Bottle blowing machine companies urgently need the direction of green, environmental protection, quality optimization, and high energy. How to better develop the safety, health and environmental protection blow molding machine profession. In the severe pollution of the 21st century, only the combination of environmental protection and zero pollution can better continue to increase the occupation of bottle blowing machines.

  2. The blow molding machine profession now focuses on Taizhou, Cangzhou and Foshan. Although the plan is small, it is not enough to compete internationally. Our blowing machine companies need to establish a brand. Only to build the brand, the bottle blowing machine goes abroad and goes to the world.

  3.The secondary utilization of the bottle blowing machine. Because new blow molding machines are expensive, second-hand blow molding machines are the first choice for small businesses. However, because it is used, the quality cannot be guaranteed, and the seller cannot provide warranty, so part of the order is restricted. Establish a trading platform for second-hand blow molding machines to burn eyebrows.
